However, the target product 2H-MoTe<sub>2</sub> from Mo precursor suffers from long growth time and suboptimal crystal quality, and MoO<sub><em>x</em></sub> precursor confronts the dilemma of unclear growth mechanism and inconsistent growth products.

Due to the high BDS ∼800 kV/cm and low <em>P</em><sub>r</sub> <strong>∼</strong>0.58 μC/cm<sup>2</sup>, high-entropy SP-RFE (La<sub>0.05</sub>Ba<sub>0.18</sub>Sr<sub>0.18</sub>K<sub>0.115</sub>Na<sub>0.115</sub>Ca<sub>0.18</sub>Bi<sub>0.18</sub>)TiO<sub>3</sub> (LBSKNCBT) MLCCs exhibited high <em>U</em><sub>rec</sub> ∼6.63 J/cm<sup>3</sup> and excellent <em>η</em> ∼ 96%. What's more, LBSKNCBT MLCCs with high-entropy and SP-RFE characteristic also possess a good temperature and frequency stability. In a word, this work offers an excellent paradigm for achieving good energy-storage properties of BaTiO<sub>3</sub>-based dielectric capacitors to meet the demanding requirements of advanced energy storage applications.</p></div>","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"11 1","pages":"Article 100860"},"PeriodicalIF":8.4,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352847824000650/pdfft?md5=db4b5d7f279abe074d492bcedb27cd7a&pid=1-s2.0-S2352847824000650-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140780481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
